How does the conductivity of printing platinum paste change with the thickness of printing?

In high-tech fields such as microelectronics, sensors, and fuel cells, printed platinum paste is highly favored due to its excellent conductivity and chemical stability. Advanced Institute (Shenzhen) Technology Co., Ltd., as a leader in this field, has won wide recognition in the market for its excellent performance in the research and development of platinum brand YB8207 printing platinum paste. This article will delve into how the conductivity of printed platinum paste varies with printing thickness, and combine it with the findings of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand YB8207 Printing Platinum SlurryConduct a specific analysis.

The influence of printing thickness on conductivity

Initial stage: Rapid increase in conductivity

In the initial stage of printing platinum paste, as the printing thickness increases, the conductivity will sharply enhance. This is because thicker printing layers can accommodate more platinum particles, thereby increasing the contact area and conductive pathways between particles. Experimental data shows that when the printing thickness increases from 1um to 5um, the resistance value of the conductive line decreases from 100 ohms to 20 ohms, indicating a significant improvement in conductivity.

Stable stage: Conductivity tends to stabilize

However, as the printing thickness increases to a certain extent, the growth trend of conductivity will gradually stabilize. This is because as the thickness increases, although the number of platinum particles increases, the contact between particles may not continue to improve significantly. In addition, excessively thick printing layers may also cause uneven drying and particle agglomeration, thereby affecting the conductivity performance. Experiments have shown that when the printing thickness increases to the range of 20um to 25um, the fluctuation range of the resistance value of the conductive line is within ± 2 ohms, and it almost no longer changes with the increase of thickness.

Performance of YB8207 Printing Platinum Slurry under the Research Platinum Brand

Viscosity and fluidity

Research Platinum Brand YB8207 Printing Platinum SlurryIt has moderate viscosity (1000-1500 cP) and good flowability, which enables it to evenly distribute and quickly fill the gaps in the screen during the printing process, forming clear patterns. This excellent printability provides a strong guarantee for obtaining uniform and stable printing layer thickness. Experimental data shows that the viscosity variation range of YB8207 paste is relatively small at different printing thicknesses, which helps to maintain stable conductivity.

Drying and sintering characteristics

YB8207 slurryThe drying and sintering conditions are mild and easy to control. Drying at 150 ° C for 10 minutes, then sintering at 600 ° C for 15 minutes, the slurry can quickly dry and form a good conductive film. This stable drying and sintering characteristic helps ensure good contact between platinum particles and continuity of conductive pathways. Experimental data shows that under these conditions, the resistance values of conductive lines exhibit good consistency at different printing thicknesses.

Conductivity performance data

according toAdvanced Institute (Shenzhen) Technology Co., LtdThe experimental data, obtained using the YB8207 printing platinum paste from Yanbo brand at different printing thicknesses, shows the following conductivity performance data:

• Printing thickness: 5um
  • Conductivity: Low (resistance value of about 20 ohms)
  • Reason: The contact area between platinum particles is limited
• Printing thickness: 15um
  • Conductivity: significantly improved (resistance value of about 5 ohms)
  • Reason: The contact area between platinum particles increases, leading to an increase in conductive pathways
• Printing thickness: 25um
  • Conductivity: tends to stabilize (resistance value is about 4 ohms)
  • Reason: Although the number of platinum particles continues to increase, the improvement in contact conditions is limited, and problems such as uneven drying and particle agglomeration may occur

conclusion

in summary,Printing platinum pasteThe conductivity of the material will undergo a process from rapid enhancement to stabilization as the printing thickness increases. In practical applications, it is necessary to choose the printing thickness reasonably according to specific needs to achieve the best conductivity performance. The YB8207 printing platinum paste of Advanced Institute (Shenzhen) Technology Co., Ltd. has shown broad application prospects in the fields of microelectronics, sensors, and fuel cells due to its excellent viscosity, fluidity, drying and sintering characteristics, and stable conductivity.
